Please Subscribe here, thank you!!!F (x) = ax 2 bx c are given by the quadratic formula The roots of a function are the xintercepts By definition, the ycoordinate of points lying on the xaxis is zero Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax 2 bx c = 0 We can do this by completing the square as,We want to find the vertex of this parabola The vertex is on the axis of symmetry, so its $x$coordinate is 3 The vertex is also a point on the parabola, so it satisfies the equation for the parabola This means that if you plug the $x$coordinate of the vertex into the equation, you will get the $y$coordinate Plugging 3 for $x$ into $y=x^26x$ gives $y=(3)^26(3)$ → $y=918$
